Does finasteride help hair growth?

According to the official data over a year 2017, the gains from the sales of products for the treatment of alopecia in the USA were more than 2 billion dollars. By the projections of experts, in 2024, this rate will grow by two times. It happens due to the growth of the popularity of Finasteride which is for sale for the treatment of alopecia, and many stories may be found on the internet that Propecia helps to return healthy hair. But is this true?

How does Finasteride help to stop alopecia?

Finasteride is a selective inhibitor of 5 alpha reductase, an enzyme which is responsible for the transformation of testosterone into dihydrotestosterone. This process leads to the reduction of the serum DHT by 70% in the hair follicles, and by 85-90% in the prostate. DHT provides a bad influence not only on the hair follicles but also on the prostatic gland causing its inflammation. The action of Finasteride is aimed only on the reduction of dihydrotestosterone, and so it does not influence on the concentration of other hormones in the blood plasma and body tissues.

The mechanism of the action of Finasteride consists in a recovery of the nutrition of the hair follicles during the decrease of the DHT level. If the hair follicle does not die and is not covered with the connective tissue, there are high risks that it will be restored within 6 months, and hair is produced within a year.

Finasteride does not provide a direct influence on the hair growth. Do not listen to people who say that this ingredient causes an improvement of the hair growth. It just restores a normal work of the hair follicles, and if they are still able to generate hair, it will happen. Also, the use of Finasteride helps to protect the healthy hair follicles against dihydrotestosterone.

Finasteride cannot also increase quantity of hair because it depends on genes. You will have as much hair as you have hair follicles. This drug does not affect the quantity of the hair follicles.

According to the estimation of the experts, 90% of men taking Finasteride stopped the hair loss, and more than 72% of men restored the hair growth on the head.

  • Finasteride does not influence on the hair growth on the body.

The matter is that DHT spreads oddly in the body and it is concentrated in the hair follicles on the body in a lower amount. Therefore, in case of the androgenic alopecia, men lose hair on the chest, arms and legs.  

Finasteride to treat benign prostatic hyperplasia

Finasteride is very valuable for men at the age of over 45. A risk of the benign prostatic hyperplasia grows at this age. Alopecia and benign prostatic hyperplasia often occur at the same time, and it is related to the increased production of dihydrotestosterone.

The use of Finasteride helps to achieve the double effect: to treat the alopecia and reduce the symptoms of the prostatic hyperplasia (to relieve the outflow of urine and reduce sizes of the glandular tissue).

Finasteride does not provide a vasodilator action, does not have the anti-inflammatory effect, and therefore the therapy of the prostatitis should be supported by the NSAIDS. But unlike these anti-inflammatory products that reduce the symptoms of the pathology, Finasteride acts on a cause and blocks the transformation of dihydrotestosterone.

An estimation of the usefulness of Finasteride should be done only on the basis of the blood test results. If the DHT level of men is high, it is recommended to start taking Finasteride in the dose of 1 mg per day to prevent the possible complications. Such preventive therapy may last from 3 to 6 months and will help you to be in a good shape.
